The goal of the current study was to create and assess the effectiveness of a hand-pulled ergonomically designed flame weeder. The developed weeder was tested in the field at three operating pressures (20, 30 and 40 Psi) and forward speeds (1.00, 1.25 and 1.50 km/h) to study their effects on plant damage, survival rates, weight preservation rates, weed management effectiveness, soil temperatures, and gas and energy consumption. Thereafter, at optimized values of forward speed and operating pressure, a comparative assessment of flame weeding with traditional methods (mechanical and manual weeding) was done in terms of weed control effectiveness, operational time, energy consumption, and cost of operation. Results showed that the optimal performance of the designed flame weeder was achieved when operated at a speed of 1 km/h and an operating pressure of 40 psi. The survival rate, weight preservation rate, weed control efficiency, change in soil temperature, recovery rate, plant damage, gas consumption, and energy consumption were observed to be 27.3 %, 32.5 %, 91.1 %, 40.74 °C, 8.5 %, 2.2 %, 4.05 kg/h, and 2500.24 MJ/ha, respectively, at optimized values of forward speed (1.00 km/h) and operating pressure (40 Psi). The actual field capacity, field efficiency and operating cost of the flame weeder were 0.0755 ha/h, 94.94 %, and 3620.81 ₹/ha, respectively. Hand weeding had the best level of weed control effectiveness, but it was a laborious, time-consuming process. When compared to manual weeding, flame weeding was 50.42 % cheaper and 94.82 % faster.
本研究的目的是制造并评估一种手工拉动的、符合人体工程学设计的火焰除草机的有效性。所开发的除草机在田间以三种操作压力（20、30和40磅力/平方英寸）和前进速度（1.00、1.25和1.50千米/小时）进行测试，以研究它们对作物损害、成活率、重量保持率、杂草管理效果、土壤温度以及气体和能源消耗的影响。此后，在前进速度和操作压力的优化值下，就杂草控制效果、操作时间、能源消耗和操作成本对火焰除草与传统方法（机械除草和人工除草）进行了对比评估。结果表明，当以1千米/小时的速度和40磅力/平方英寸的操作压力运行时，所设计的火焰除草机可实现最佳性能。在前进速度（1.00千米/小时）和操作压力（40磅力/平方英寸）的优化值下，观察到成活率、重量保持率、杂草控制效率、土壤温度变化、恢复率、作物损害、气体消耗和能源消耗分别为27.3%、32.5%、91.1%、40.74℃、8.5%、2.2%、4.05千克/小时和2500.24兆焦/公顷。火焰除草机的实际田间作业能力、田间效率和操作成本分别为0.0755公顷/小时、94.94%和3620.81卢比/公顷。人工除草的杂草控制效果最佳，但这是一个费力、耗时的过程。与人工除草相比，火焰除草便宜50.42%，速度快94.82%。
